ACOUSTA-WAL® is available
in Type IV units. Type IV units outperform the previously
manufactured Type II and Type III units. Use Type IV Units
for broad range sound absorption, such as school gymnasiums,
lecture halls, and performing art centers.
Available in 4” or 6” thicknesses, Type
IV units have wide funnel-shaped slots, opening into
a two chamber cavity separated by a metal septum laminated
to a factory-inserted fiberglass filler. Fiberglass fillers
are chemically inert, vermin resistant, incombustible
and moisture-proof.
